REGISTER-GUIDE AND GBIPPER.

Specification of Letters Patent.

Patented June 3, 1912.

Application led March 9, 1918. Serial No. 221,541.

To all whom it may concern Be it known that I, MAYNARD T. JOY, a citizenof the United States, and a resident of the city of New York, borough ofManhattan, in the county and State of New York, have invented a new andImproved Register-Guide and Gripper, of which the following is a full,clear, and exact description.

This invention relates to guides for printing presses and has for anobject the provision of an improved combination guide and gripperforguiding paper to a correct position and holding the same in saidposition.

Another object in View is to provide a gripper arm with an extendingportion to act in the usual capacity of an arm, and a reduced portiontogether with a movable guide, the parts being so arranged that when thegripper arm moves to a position on the platen during the printingoperation the guide will automatically move for shifting properly thepaper on the platen.

A further object in view is to provide a movable guide formed in such amanner as to push a piece of paper on the platen at rst rapidly and thenslowly until thepaper has been moved to the correct position forprinting.

Another object is the provision of an adjustable guide formed withgripping means for engaging the paper so as to prevent any momentumthereof when being moved to the correct printing position.

In the accompanying drawings:

Figure 1 is a fragmentary perspective view of a platen and gripper bartogether with an embodiment of the invention applied thereto. i

Fig. 2 is a top plan view of the guide and associate parts shown in Fig.1.

Fig. 3 is a view similar to Fig. 2, but showing the parts in theiroperated position.

Fig. 4 isa sectional view through Fig. 2

i on line 4 4.

Fig. 5 is a sectional view through Fig. 3 on line 5-5.

Referring to the accompanying drawings by numerals, 1 indicates a platenof any ordinary kind on any suitable form of press said platen beingprovided with a lower guide 2 for properly supporting the paper 3 whenplaced in position. Associated with Y theplaten 2 isa gripper bar 4 of,any usual preferred structure, said gripper bar having a base 5 clampedthereto in any suitable way, as for instance by the bolt 6, said basebeing preferably formed integral with the gripper arm 7, which armextends partly across the platen 1 when the press is closed. The arm 7is offset slightly at 8 for clearing part of the movable guide 9. Thismovable guide is formed as more particularly shown in Figs. 2 and 3 andis connected to the base 5 of the gripper arm 7 so as to beautomatically operated as the gripper bar and arm move in the usual way.A hinge 10 is mounted on the base 5, said hinge acting to :connect thepower rod 11 with base 5 so as to move the power rod at the proper time.The frame 12 of the guide 9 preferably consists of a flat piece of metalhaving an offset 13 at one end which is formed into part of a hinge, oras a plate 14 connected therewith, formed with upstanding ears throughwhich the pintle 15 passes, said pintle also passing through a pair ofears 16 connected to the cross-bar 18, which cross-bar in turn isriveted or otherwise secured to the base 5. It is, of course, understoodthat base 5 could be formed with ears and the frame 12 with earsindependent o f the eXtra bars 14 and 18 without departing from thespirit of the invention, provided these earsvwere formed so as toaccommodate the pintle 15 and a spring 17. The pintle 15 is preferablyin alinement with the journal pin 18 of bar 4 so that when the bar 4moves frame 12 will not move though the hinge 10 will move and willconsequently move the rod 11 longitudinally. In this way the frame 12 isconnected through the base 5 to gripper bar 4, and movement is given tothe rod 11 so that the parts-hereinafter fully described will beoperated for properly shifting the sheet 3 as the press is operated. Aguide 19 for rod 11 is preferably rigidly secured to the frame 12 and isprovided with an overhanging hook section 21 whereby the rod 11 mustmove back and forth in a given path so as to operate the toggle levers22 and 23. Lever 22 is preferablydouble so that lever 23 may bejournaled therebetween, and in that way give a direct thrust without anyside movement. The lever 23 is rpivotally mounted at 24 on a suitableprojection 25 and secured in any suitable way to frame 12, or formedintegral therewith. The lever22 is pivotally -connected to an extension26 on the slide 27 which slide is slidingly mounted between the guideplates 28 and 29 and between the end ofl the frame 12 and end-block 30.These guiding members act to cause slide 27 to move back and forthatright angles to the frame 12. A Y

spring holding plate 31 is rigidly secured in any suitable manner, asfor instance byl as shown in Fig. 5. In this way the pusher guard 36will mofve the paper and the spring acting through the curved end 35will prevent any momentum of the paper so that the movement of the paperwill stop immediately upon the stopping of the guide. This question ofmomentum has also been taken care of by the arrngement of the togglelevers 22 and 23 which at first move the slide 27 and the guide 36rapidly, but which gradually slows down until it stops at its extremeouter movement. The pusher guide 36 is provided with an overhangingbifurcated extension 37 which accommodates the screw 38 tted into slide27 whereby the pusher may be adjusted independentlyl of the other partsand thereby take care of any slight difference in the position of thepaper 3 without molesting the clamping 'bolt 6. It is, of course,understood that the clamping bolt 6 may be removed and the partsadjusted longitudinally of the bar t to any desired extent," thoughwhere a small or fine adjustment is desired the movement of theextension Vor plate 37 after alining screw 38 is usually necessary. Inusing the device the paper is always fed downwardly against the guide orguides 2 and also against the movable guide 9. Usually it iscomparatively easy to cause the lower edge of the paper to rest on theguide or guides 2, but it takes some considerable skill and also time toproperly fit the end edge of the paper against the end guide. In thepresent instance if the paper engages the lower guides th-e pusher guide36 will move the paper over to the correct position to cause a properregistry, and usually if the paper is not quite correctly engaging thelower guides the lateral movement will cause the paper to act undergravity and engage these guides so that a more or less inexperiencedperson may be used to feed the paper and exact registry secured. Whereprinting is done in av single color often times exact registry is notessential,l though always desirable. In printing in colors however anexact' registry is not only desirable, but essential, and it is alsoextremely desirable to keep the press going at a certain speed in orderthat a proper quantity of ink may be supplied for each impression and amovement of the feeder. r1`he guide 9 will always engage lthe edge ofthepaper as the pusher 36 is preferably formed with a slightly sharpenededge 39 as shown in Fig. 5 and the lcurved end 35 will prevent anymomentum created in' the paper even though the press is runningatcomparatively high speed. Referring to Figs.l 4L and 5 itwill be seenthat the spring 36 extends through a suitable notch 40 centrally of thepusher 36. In addition to accomplishing the desired result of preventingmomentum in the paper the spring by its shape and action vwill flattenor straighten out paper that is curved somewhat or bulged somewhat wheninserted. In accomplishing` this result it willV be noted that thespring extends overt-he paper and is pressed downwardly against thepaper by the l.pusher 36 so that the spring will properly straighten thepaper out as well as to engage the same in such a way as to preventVmomentum, all

of which is done quickly, easily, and automatically, and in proper timedrelationship to the speed of the press.
